# UnifiedFiler v1.9.7-fix3 Notes

## Purpose

This patch clarifies and enforces the frontend-only Google Drive integration direction.

## Changes

- Removed `demo/server.js` from the package.
- Reaffirmed that Google Drive upload uses only browser JavaScript:
  - Google Identity Services token client
  - OAuth access token stored in browser memory
  - Google Drive API v3 calls through `fetch`
  - multipart / resumable uploads directly to Google Drive
- No backend proxy, server-side upload endpoint, or client secret is used.
- Kept the single-flight authorization improvement introduced in v1.9.7-fix2.
- Updated documentation so COOP notes are treated as Host browser-environment guidance only, not as a UnifiedFiler server requirement.

## Important note

UnifiedFiler should be served by the Host as normal static frontend assets. The Google Drive feature itself must remain frontend-only and must not depend on package-provided server code.
